Coated carbon nanotubes coated with 0.01-100 parts by weight of at least one type of aromatic condensation polymer selected from the group consisting of wholly aromatic polyamides, wholly aromatic polyesters, aromatic polyester carbonates, aromatic polycarbonates, semi-aromatic polyesters and wholly aromatic azoles, with respect to 100 parts by weight of the carbon nanotubes, as well as a process for their production. Aromatic condensation polymer compositions comprising 0.01-100 parts by weight of the coated carbon nanotubes and 100 parts by weight of an aromatic condensation polymer, and molded articles formed using them.

Carbon nanotube coated with aromatic condensation polymer

A medical material composed of a poly(alkyl aryl ether)sulfone copolymer (A) and a thermoplastic polymer (B), such as cellulose triacetate, and being used in contact with the blood, wherein the concentration of the copolymer (A) is at least 40% by weight at least near the surface of a part having a surface to be used in contact with the blood and the copolymer (A) is a specified polysulfone bearing fluorine atoms and polyalkyl ether units and which is suitable for a hollow fiber membrane for artificial kidneys, and the like.

Medical material containing fluorinated polysulfone having excellent antithrombotic activity

A novel polyalkyl ether/polyaryl ether sulfone or ketone copolymer and a specific polyether ester copolymer are useful for producing a medical material to be used to contact the blood; and methods for producing the medical material comprising said polyalkyl ether/polyaryl ether sulfone or ketone copolymer or a specific polyether ester copolymer.

Application of sulfone, ketone and ester containing polyalkyl ether

A blood dialyzer is produced by a process in which a plurality of artificial composite fibers having core portions consisting of a water-insoluble core liquid and surrounded by sheath portions consisting of a fiber-forming polymer are subjected to a removal of almost all of the core liquid; the resultant hollow fibers are bundled; the hollow fiber bundle is packed in a cylindrical case having open end; end portions of spaces left between the hollow fibers peripheries and between the hollow fibers and the inside surface of the cylindrical case are sealed with a bonding material, to fix the hollow fiber bundle to the cylindrical case at the end portions thereof; and the hollow fibers in the cylindrical case are cleaned with a cleaning liquid comprising at least one aliphatic monohydric alcohol having 3 to 8 carbon atoms.
